Leydig, Voit & Mayer, LTD.

Leydig, Voit & Mayer, LTD., a for-profit intellectual property law firm headquartered in Chicago, Illinois, operates as a prime contractor delivering specialized patent legal services to the National Institutes of Health and related federal research agencies, competing exclusively in full-and-open procurement with no set-aside designations. The firm's federal footprint spans five thousand five hundred sixteen awards across thirty years, with 100 percent prime-contract participation and zero subcontractor engagement, reflecting a practice model in which the firm builds and staffs its own delivery teams entirely from internal resources.

Leydig, Voit & Mayer's capability portfolio centers on patent prosecution, patent application preparation and filing, prior art searches, conflict-of-interest reviews, and general intellectual property counsel across biotechnology, chemistry, mechanical engineering, and software technology domains. Representative work includes a $1.38 billion time-and-materials delivery order from the National Cancer Institute (June 2024) for patent legal services in chemistry; an $8.89 million time-and-materials delivery order from the National Cancer Institute (June 2024) for biotechnology patent legal support running through June 2027; a $15,671 firm fixed-price delivery order from the NIH Office of the Director (September 2026) for patent and legal services supporting the National Heart, Lung, and Blood Institute; and a $888,800 time-and-materials delivery order from the National Cancer Institute (June 2024) for mechanical engineering patent legal services. Smaller delivery orders in the $10,000–$20,000 range dominate the contract mix, supporting routine patent filing, provisional application preparation, Patent Cooperation Treaty filing, national stage patent applications in multiple jurisdictions, and design document preparation across dozens of NIH institutes and centers.

Customer concentration sits entirely within HHS NIH. The top five funding entities account for 94 percent of award count, dominated by the NIH Office of Logistics and Acquisition Operations (two thousand five hundred twenty-two awards, $1.08 billion combined potential value) and the NIH Office of the Director (two thousand two hundred fifty-nine awards, $19.5 million combined potential value), followed by the NIH as a whole entity (three hundred thirty-two awards, $8.73 billion combined potential value). By potential-value ranking, the NIH entity (as a consolidated customer) accounts for $8.73 billion (61 percent of total), the Office of Logistics and Acquisition Operations for $1.08 billion (8 percent), and the National Cancer Institute for $25.6 million across ten large delivery orders spanning biotechnology, chemistry, software, and mechanical engineering. The vendor operates entirely through the NIH Patent Legal Services master IDIQ, a $552 million vehicle issued in April 2020 covering four technology categories; one hundred fifty-nine task orders under this vehicle carry a combined potential value of $25.4 million. Three other IDIQs (HHSN263200900008I, HHSN263200900023I, and 263020024) account for over five thousand task orders collectively, though the source distinguishes these as related vehicles within the NIH acquisition structure.

Activity has remained modest and consistent year over year: seventeen awards in 2022, twenty-two in 2023, thirty-two in 2024, twenty-five in 2025, and two through September 2026 in the source data. Seven awards totaling $11.9 million in combined potential value reach ultimate completion inside the next twenty-four months, presenting a modest recompete exposure for the vendor and a limited window for competitive displacement. The vendor has registered in SAM.gov since 2003 and maintains no federal contract sub-awards; all five thousand five hundred sixteen awards are prime-contract positions.

SCI-reported invoicing across federal service contracts above the $150,000 threshold totaled $12.1 million across fiscal years 2022 through 2025, with FY2024 peak invoicing of $3.4 million against 2.7 full-time equivalents. Median government-paid rates on SCI-reportable prime contracts ran around $550.53 per hour, with rates spanning from approximately $455 per hour at the tenth percentile to approximately $649 per hour at the ninety-th percentile, reflecting a range consistent with senior-level intellectual property counsel. SCI data shows zero subcontractor-hour engagement; the firm delivers all federal legal services using internal personnel only. The firm operates a lean staffing model, with annual FTE counts hovering between 2.0 and 2.7 individuals assigned to federal patent legal work, yielding approximately $1.2 to $1.7 million in annual SCI-reportable invoicing per FTE—a benchmark consistent with high-billable-rate specialized legal counsel.
